Why? Is ATC a problem in other countries than the US? Are they also under training pilots? If anything RyanAir with its flamboyant history of cost cutting (CEO always threatening to charge for use of the onboard lavatory) seems a more likely source than the flying infrastructure itself.
Ryanair has a very good safety history, among the highest in the world.
They make outrageous claims for publicity, and their customer experience is all about hidden extras and "gotcha" pricing, but I don't think they fuck around when it comes to safety.
They know that with their reputation they would be sunk if they did have a major incident.
It's both true that Ryanair has very good safety record, and that in the past there were incidents with them landing on low fuel.

> In 2012 and 2013 “Brandpunt Reporter” broadcasted a two episode TV investigation in which Ryanair pilots, speaking anonymously, raised concerns about the airline’s fuel policies and company culture. The pilots revealed that the company may be exerting pressure on them to minimize the amount of fuel they take on board – a practice which limits significantly the fuel costs for the company but could jeopardise safety in certain circumstances. The direct reasons for this broadcast were 3 emergency landings of Ryanair aircraft in Valencia Spain on the 26 July 2012, within a short timeframe due to low fuel levels.
So it's sunk? They just had a major incident.
Let's wait for the investigation results before coming to that conclusion.
